ACC commissioner John Swofford told ESPN this week that there is "considerable support" for a nine-game league schedule, though nothing is imminent. But the SEC idea is a new one.

The SEC is looking to finalize a scheduling format that will kick off for the 2016 season, when the SEC and ACC will be the only major conferences without a nine-game schedule. The SEC is also considering a similar agreement with the Big 12, but these types of deals have occurred in the past without ever coming to fruition.

Exactly. RT @Alex_MnB: @slmandel The B1G / P12 agreement was announced and then eventually cancelled. This one probably won't happen either

The plus-one idea is still in the discussion phase, however, and at least one source told ESPN it's unlikely all SEC programs would voice support.

The SEC source said he did not see a scenario to which all 14 SEC schools would agree, but there may be one in which the SEC could match some teams against the ACC, particularly if those SEC teams were having trouble finding suitable BCS nonconference opponents.
